While in cruise flight at 5,000 feet the pilot heard a loud bang, followed by an instantaneous increase in RPM. Subsequent attempts to sustain engine power with throttle and propeller inputs were unsuccessful, which resulted in the pilot attempting a forced landing to a paved runway approximately 4 miles away. The airplane subsequently impacted the last row of trees of an orchard less than one-half mile from the end of the runway, which resulted in the airplane coming to rest on its belly oriented on an easterly heading. A post accident examination of the airplane's engine revealed that all three planetary gears were severely damaged, and all three gears appeared to have lost all gear teeth, with a portion of the gear teeth located in the oil sump. The reason for the damage to the planetary gears was not determined.
Probable Cause: The failure of the engine's three planetary gears for undetermined reasons. A factor contributing to the accident was the tree orchard.
